R-410A pressure temperature chart

R-410A PT table

Use the PT chart to read saturation temperature from a gauge pressure reading, then compare that value with the equipment targets. A metric view can be shown alongside pressure in psig and temperature in F, and the chart should name the source document and revision used.

For a broader overview, see the PT chart index and the glossary.

Bubble point and dew point

For blends, bubble point is used for subcooling and dew point is used for superheat. This matters because a blend can show a small temperature glide, so the correct point keeps the reading aligned with the measurement you are trying to make.

See also the refrigerant transition guide.

Using the R-410A chart with gauges

Use the chart with your manifold gauges to compare measured pressure against saturation temperature, then confirm the target on the system data plate. Superheat and subcooling should be checked against the equipment instructions rather than guessed from the chart alone.

If you want a related workflow, try the superheat and subcooling calculator or join the waitlist.

R-410A safety and handling notes

Before servicing, follow the safety class and recovery steps listed by the manufacturer and your local requirements. Do not vent refrigerant, and use proper recovery equipment and procedures for any system service.

Compare with other refrigerants

R-410A is often compared with other blends during equipment replacement and retrofit planning. If you are checking a different refrigerant, use the matching chart for that refrigerant rather than assuming the same pressure temperature relationship.
